Kevin,

I will second the info that Ben gave you.  Although it has not happened to me 
with the same frequency as to Ben, I too have had idle problems with an early 
90s Chrysler 3.3l mini-van engine.  The problem comes and goes, when coming to 
a 
stop, then engine speed drops, or the engine stalls.  When everything is 
working 
well, the engine speed is remarkably stable.  When the Idle Speed Control is 
not 
working well the idle speed is eratic.

When I removed the ISC, it was not all that dirty, but after cleaning it the 
problem was solved.

Good luck.

-Roger
